Cov hlau sawb - kom grounding

Yuav kom txo tau cov teebmeem ntawm hluav taws xob tam sim no, piv txwv li, los ntawm xob laim, siv ib tug tshwj xeeb hlau sawb: galvanized los yog stainless hlau. Nws kuj yog siv raws li ib tug laim qws tshwj xeeb uas txais cov chaw thiab txo txoj kev pheej hmoo ntawm tam sim no raug rau cov neeg uas tej zaum yuav nyob ze rau qhov ntau lawm cov khoom ntawm ib tug ua tau hluav taws xob yuam kev. Xws li ib tug cov ntaub ntawv uas yog yuav tsum tau raws li kev tiv thaiv ntau yam nyob ntawm tej thiab cables uas yog nyob rau hauv chav tsev ceg. Ntxiv mus, xws li ib tug sawb tej zaum yuav tsum muaj ntaub ntawv mus rau lub tso zis voltage nyob rau hauv cov kab. Qhov no yuav pab ua rau kom cov durability ntawm cov kav dej, thiab yog li thiaj li muaj cov yam ntxwv ntawm corrosion.

Nws yuav tsum tau muab sau tseg tias hlau sawb yuav siv tau los txo cov kev pheej hmoo ntawm hluav taws xob poob siab rau cov neeg thiab kom tshem tawm cov lawm tab lim. Ua li no, nws tsim ib tug vicious vajvoog ntawm loj loj, uas yog teev nyob rau hauv cov av nyob rau ib lub tob ntawm 0.5 meters nyob ib ncig ntawm lub perimeter. Vim hais tias ntawm cov txheej ntawm cov hlau sawb nrog zinc los yog stainless steel tsub kom nws pab cuam lub neej ntawm 30-50 xyoo.

Thaum uas siv cov hluav taws xob muaj yog ib txwm ib tug siab ntau yam ntawm tshwm sim ntawm yus lub sijhawm rau tib neeg. Yog li ntawd, nyob rau hauv kev txiav txim kom tsis txhob muaj teeb meem siv ib tug hlau sawb - ib tug txhim khu kev qha twj yuav tsum tau siv nyob rau hauv kev hluav taws xob nyob rau hauv lub tsev thiab nyob rau hauv kev lag luam. Yuav kom av tus xauj tsev nyob rau hauv lub tsev, tshwj tsis yog rau ib tug sawb, koj yuav tsum yuav lub hwj chim faib vaj huam sib luag, earthing, thaiv thiab hluav taws xob khoom siv.

Nyob rau hauv tas li ntawd, cov hlau sawb yuav siv tsis tau rau grounding thaum lub ntuj grounding muaj nyob rau hauv lub tsev muaj kev ruaj ntseg: kav xa dej, tsev ntas (ua los ntawm cov hlau), tab sis yog hais tias lawv muaj nyob rau hauv kev sib cuag nrog cov av, raws li tau zoo raws li lub zoo yeeb nkab. Thaum uas siv cov xws tej yam ntuj tso ntiaj teb electrodes yuav tsum tso saib ib tug tshwj xeeb qhov hluav taws xob, namely rau nteg tshwj xeeb grounding hlau mus rau lub qhov hluav taws xob kev siv ntawm cov log tsheb. Luj Tshib koom los ntawm bolts los yog welding.

Rau earthing ntaus ntawv yog thawj tsim nyog los khawb ib trench, uas yuav kis tau los ntawm cov kwv mus rau ib tug tshwj xeeb contour qhov chaw. Nyob rau hauv qhov chaw ntawm lub Circuit Court trench yuav siv rau hauv daim ntawm ib tug daim duab peb sab ntawm txhua kab los sib ntsib ntawm cov uas yog tsim nyog rau tho qhov zoo mus rau ib tug tob ntawm peb meters. Ces haum lub stainless steel sawb los yog zinc plated thiab hammered steel rods. Ces tag nrho cov qauv yog them nrog ib tug txheej ntawm lub rho av, uas yuav tsum muaj tseeb ntawm cov khib nyiab thiab rubble. Yuav kom txo tau cov kuj ntawm lub Circuit Court, nws yog ntxiv txuas mus rau lub laj kab ntawm ib tug hlau los yog kev txhawb zog. Welded nqaws yog them nrog bituminous xim los tiv thaiv corrosion.

Thiab thaum kawg, yog hais tias los ntawm cov huab cua kis tau tus mob kab mus rau lub tsev tuav peb theem hluav taws xob, ces siv tsis tau tsuas yog rau cov grounding sawb, tab sis kuj ntxiv tshuaj - nruab nrab neeg xyuas pib nyob rau hauv lub tswv yim mus rau lub hwj chim vaj huam sib luag. Qhov no ntaus ntawv yog yuav tsum tau txuas mus rau lub earthing Circuit Court. Heev yooj yim thiab yig nyob rau hauv cov nqe lus ntawm cov nyiaj ua lub contour yog nyob rau theem ntawm tso lub hauv paus los yog kua system.
